ADJUSTABLE SHADE-BRACKET.

Specification of Letters Patent.

Patented Oct. 18, 1910.

Application filed September 15, 1909. Serial N 0. 517,941.

To all whom it may concern:

Be it known that I, JAMES M. MAYS, a citizen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inAdjustable Shade Brackets, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to adjustable curtain shade roller supports, andthe objects of my invention are to provide positive and re liable meansfor adjustably holding a curtain shade roller in connection with thewindow frame, and to furnish a window frame with means whereby thecurtain shade roller can be easily raised or lowered and held in anadjusted position.

Other objects of my invention are to pro vide a curtain shade rollersupport that will not sag or become displaced when adjusted, and toaiford novel means for adjusting the support to window frames of varioussizes.

Further objects of my invention are to ac complish the above results bya strong and durable fixture easily applied to a window frame, and toprovide a support of the above type that will be comparativelyinexpensive to manufacture and highly efficient for the purposes forwhich it is intended.

These and such other objects as may hereinafter appear are attained bythe mechanical construction shown in the drawing forming a part of thisspecification, wherein there is illustrated the preferred embodiments ofmy invention; but it must be understood that the structural elementsthereof can be varied or changed, as to the size, shape and manner ofassemblage without departing from the spirit or scope of the invention.

In the drawing :-Figure l is a front ele vation of a portion of a windowframe equipped with my improved curtain shade roller support, Fig. 2 isa vertical sectional view of the support on the line 00-00 of Fig. 1,Fig. 3 is a longitudinal sectional view of a portion of one of therevoluble shafts of the holder, Fig. 1 is a plan of a portion of theholder, Fig. 5 is a longitudinal sectional view of a portion of amodified form of plate, Fig. 6 is a plan-of a modified form of holder,Fig. 7 is a horizontal sectional view of a modified form of rack adaptedfor use in connection with the holder, and Fig. 8 is a perspective viewof a clip used in connection with the holder.

In the drawing 1 denotes a window frame having the inner sides thereofadjacent to the upper sash 2 provided with vertical racks 3 and J-shapedguide strips 4, said strips and said racks being secured to the frame bysuitable fastening means, as screws 5.

6 denotes a plate having the upper and lower edges thereof provided withlateral oppositely extending flanges 7 and 8. The ends of the plate 6are provided with the conventional form of brackets 9 for revolublysupporting a curtain shade roller 10. The rear side of the plate 6 isprovided with brackets 11 having hook shaped vertical edges 12 adaptedto engage the guide strips 1 of the window frame. Revolubly mounted inthe brackets 11 are longitudinal shafts 13 having the ends thereofprovided with pinions 14 adapted to mesh with the vertical racks 3. Theracks, pinions and shafts are used to cause a uniform movement of theends of the bracket. As the bracket is only moved at one side of thewindow-frame, there would be a liability of the structure binding onaccount of the interlocking guides, but through the medium of theshafts, pinions and racks, one end of the bracket will be moved just asfar as the other end, thus insuring an even and uniform movement.

Attached to the flange 7 at one end of the plate 6 is a cord or cable 15adapted to pass upwardly over a sheave 16 revolubly supported in ahanger 17 arranged at the upper edge and to one side of the frame 1. Theend of the cord or cable is adapted to be fastened in a wire clip 18secured to the front side of the window frame 1 adjacent to the sill 19thereof.

Before further describing my invention, the following modifications willbe noted.

In Fig. 3 of the drawing, I have illustrated the shafts 13 as being madein two sections and the ends of said sections adjustably connectedtogether by a sleeve 20.

In Fig. 5 of the drawing, the plate 6 is made in two sections and theends of the sections adjustably connected by a coupling member 21. It isthrough the medium of the construction shown in Figs. 3 and 5 that mysupport can be used in connection with window frames. of various widthsto accommodate curtain shade rollers of various lengths.

In Fig. 6, the guide strips 4 are shaped so that, they can be secured tothe front slde of the window frame, while in Fig. 7 of the drawing, aguide strip and a. rack slightly different in cross sectional shape areshown. It is. in this connection that I reserve the right to shape theguide strips for w1 ndow frames of various shapes, thus permittlng of myimprovement being extensively used.

From the foregoing it will be observed that it is impossible for one endof the holder to sag or become displaced during the justment of eitherthe plate 6 or the curtain shade roller carried thereby.

The various parts of the holder are made of light and durable metaleasily shaped, assembled and applied to a window frame.

Having now described my invention what I claim as new, is

1. In a curtain shade roller support, the combination of vertical racks,guide strips carried by said racks, a plate extending from one rack tothe other, and adapted to revolubly support a curtain shade roller,brackets projecting rearwardly from said plate and slidably engaging insaid guide strips, revoluble shafts journaled in said brackets, pinionsmounted upon the ends of said shafts and meshing with said racks, andmeans connecting with one end of said plate for vertically shifting thesame upon said racks.

2. In a curtain shade roller support, the combination with racks, guidestrips projecting inwardly from said racks, brackets slidably mounted insaid guide strips, a plate connecting said brackets and having a bearingat each end for supporting a curtain shade roller, shafts revolublymounted in said brackets rearwardly of said plate, pinions carried bysaid shafts and meshing with said racks, and means connecting with plateconnecting said brackets and provided at each end with a bearing forsupporting '"a curtain shade roller, shafts revolubly mounted in saidbrackets rearwardly of said plate,'pinions mounted upon the ends of saidshafts and meshing with said racks, a sheave, a bracket at the top ofthe window frame for supporting said sheave, and a cable connecting withone end of said plate and adapted to pass over said sheave,substantially as, and for the purpose herein described.

4:. In a curtain shade roller support, a pair of racks adapted to befixed to a window-frame, guide strips projecting toward each other andinwardly from said racks, a pair of brackets each having its inner endslidably connected in said guide strips, a plate connected to the outerends of the brackets and projecting from said brackets,

said plate having each of its ends provided with a bearing forsupporting a curtain shade roller, said brackets projecting below saidplate, a pair of shafts arranged in parallelism with respect to eachother and journaled in said brackets, said shafts of less length thansaid plate, pinions carried by the ends of said shafts and meshing withsaid racks, and means connected with the plate for vertically moving thesame.

In testimony whereof I affix my signature in the presence of twowitnesses:

JAMES M. MAYS.
